Minimally invasive laparoscopic surgery has become widespread and the indications for such surgery have recently been extended to various conditions, including rectal cancer. The objective of this study was to compare the clinical outcome of hand-assisted laparoscopic surgery (HALS) and conventional laparotomy (CL) in patients with rectal cancer. Patients who underwent radical resection of stage I-III primary rectal cancer (n=111) were classified into those receiving HALS (n=57) and those receiving CL (n=54); the two groups were matched for stage and postoperative treatment. The 3-year relapse-free survival (3Y-RFS) and 3-year overall survival (3Y-OS) were calculated and compared between the two groups. Intraoperative blood loss, operating time, postoperative hospital stay and complications were also compared between the two groups. There were no significant differenceS in 3Y-RFS or 3Y-OS between the HALS and CL groups for patients with all-stage (I, II and III) rectal cancer. The mean (median) intraoperative blood loss was 344.0 (247.0) ML in the HALS group vs. 807.5 (555.5) ML in the CL group (P<0.001). The mean (median) postoperative hospital stay was 19.8 (17) and 25.5 (18.3) days, respectively (P=0.039). There were no significant differences in the operating time or the incidence of complications between the two groups. Based on these results, HALS was found to be comparable to CL regarding survival, while achieving less blood loss and a superior cosmetic outcome. However, longer follow-up is required to confirm these findings.
